Donald Trump offered London's newly elected mayor an exception to his Muslim ban.

But Sadiq Khan doesn't want it.

"Whilst it may be great he's made an exception for me, it's not about me. It's about my friends, family and others. ... He's playing into the hands of extremists who say it's not compatible to be Western and to be a mainstream Muslim. London showed last Thursday it is," Khan told the BBC.

The New York Times asked Trump if the ban would apply to Khan. He said, "There will always be exceptions."
